2021-01-21tests/tcg/s390x: Fix EXRL testsDavid Hildenbrand
The current EXRL tests crash on real machines: we must not use r0 as a base register for trt/trtr, otherwise the content gets ignored. Also, we must not use r0 for exrl, otherwise it gets ignored. Let's use the "a" constraint so we get a general purpose register != r0. For op2, we can simply specify a memory operand directly via "Q" (Memory reference without index register and with short displacement).
